A2.5kg object oscillates at the end of a vertically hanging light spring once every 0.65s .part awrite down the equation giving its position y (+ upward) as a function of time t. assume the object started by being compressed 17cm from the equilibrium position (where y = 0), and released. write down the equation giving its position ( upward) as a function of time . assume the object started by being compressed 17 from the equilibrium position (where = 0), and released. y(t)=(0.17m)? cos(2? t0.65s)y(t)=(0.17m)? sin(2? t0.65s)y(t)=(0.17m)? cos(0.65s? t)y(t)=(0.17m)? cos(t0.65s)part bhow long will it take to get to the equilibrium position for the first time? express your answer to two significant figures and include the appropriate units. part cwhat will be its maximum speed? express your answer to two significant figures and include the appropriate units. part dwhat will be the object's maximum acceleration? express your answer to two significant figures and include the appropriate units. part ewhere will the object's maximum acceleration first be attained? where will the object's maximum acceleration first be attained?
